Struct NumberStyle 

pub struct NumberStyle<'a> {
    pub decimals: usize,
    pub group: Option<char>,
    pub decimal: char,
    pub prefix: &'a str,
    pub suffix: &'a str,
}

How to write a number: decimal places, separators and text around it. This is the one place that lays out digits, for Culture and for anything with separators of its own.

use ravenrs_criteria::NumberStyle;

let style = NumberStyle { decimals: 2, group: Some('.'), decimal: ',', prefix: "R$ ", suffix: "" };
assert_eq!(style.format(-1234.5), "-R$ 1.234,50");

Fields

decimals: usize

Digits after the decimal separator.

group: Option<char>

Thousands separator, if digits are grouped.

decimal: char

Decimal separator.

prefix: &'a str

Text before the number, after the sign (e.g. a currency symbol).

suffix: &'a str

Text after the number (e.g. %).

Implementations

impl NumberStyle<'_>

pub fn format(&self, n: f64) -> String

Writes n, rounded to the style’s decimals. A value that rounds to zero has no sign.
